Combustion rate detection method for motor vehicle, involves calculating value that expresses time distance between current value of index representative of irregularities of operation in engine and estimated reference value

摘要

The method involves calculating a value expressing an instantaneous time distance before the calculation of an observation function that is expressed as a function of the distance. The distance is between a current value of an index representative of the irregularities of operation in an engine and an estimated value of reference illustrative of the index at a different instant. The current value of the observation function corresponds to the value representative of the index after exclusion and/or weighing of the values external to the preset admissible distance.
